Euro-Office is an upcoming FOSS office suite and collaborative software platform based on OnlyOffice that provides editors for documents, spreadsheets, presentations, and PDFs. The software includes web-based, desktop, and mobile applications designed for document creation, editing, and collaborative work.[3]

History

The project began in March 2026 in a quest to gain full independence from Microsoft Office being used in EU public computers.[4][5][6] The project is a collaboration between various organizations, companies, and open source developers. The original collaborators were IONOS, Nextcloud, Eurostack, XWiki, OpenProject, Soverin, Abilian and BTactic, with Office EU and Open-Xchange joining the project soon after its announcement.[7][8]

One of the first changes made to the Euro-Office codebase was to remove licensing terms deemed to be "unenforceable and non-obligatory" additions to the GNU AGPL licence.[9] Three days later, the developers of OnlyOffice responded by publicly calling these changes a licensing violation.[10][11] Soon after, OnlyOffice announced it would be suspending its partnership with Nextcloud due to the conflict.[12]

In response to these accusations, statements were issued by Nextcloud Software,[13] the Free Software Foundation,[14] and legal experts[15] asserting that both the letter and the spirit of a free software license expressly prohibit the use of license addenda to revoke the freedoms guaranteed by the original license. In the case of the addenda to the GNU AGPL license introduced by the OnlyOffice developers, they contained mutually exclusive requirements (specifically, a simultaneous prohibition on altering branding and a prohibition on the use of the trademark). The position held by the creators of the GNU AGPL—as well as by legal experts—is that restrictive supplementary clauses may be omitted from the license during redistribution; this principle is explicitly stated in Clause 10 of the original GNU AGPL license. Consequently, the developers of Euro-Office possess the full legal right to distribute the product without including these additional restrictive clauses in the accompanying license.

Products

Similar to OnlyOffice, the Euro-Office ecosystem consists of several core applications and tools designed for document editing, collaboration, and workspace management. These include:
